Phantasy Star Online Episode I&II is the game that enabled homebrew. By mimicking the game's server program, one could supply their own executable codes to the GameCube. Early dumps of GameCube disk images were created using this game. Nintendo and Sega responded by releasing Phantasy Star Online Episode I&II Plus.

Unused Graphics

All unused art is found in both the original release and Plus.

The title screen from the Japanese Trial Version of the game is present in all GameCube PSO builds, including Episode III. The title screen exists in both English and Japanese, although the Trial Version was never released outside of Japan.

A file called f256_joyboot.gvm is present in all PSO GameCube releases (including Episode III), which references the GameCube version of the game as "N-Port". It is not known what the message refers to.

Dreamcast Leftovers

The game also has some leftover assets from the Dreamcast version, including a promotional image from the Sega GameJam demo of Phantasy Star Online Version 2 (2001).
